This page outlines the capacitors that are on the boards of older Macintosh computers and where to locate them. If there are any errors please feel free to correct me.


Macintosh SE/30

Note: SMD Electrolytics can be substituted for Tantalum polymer caps provided they are correctly rated for voltage, can physically fit and due to the contact size/shape differing from the originals care must be taken to ensure that soldering them doesn't contact unwanted nearby vias. The benefits are they won't leak in the future.
